gnustep build broken

[Miles Bader <miles.bader@necel.com>]

I tried again today to build NS emacs using gnustep, and it broke pretty
early, after succeeding only to build lib-src.  Apparently it is
expecting to be build on mac-os using apple's make?

   $ make distclean
   ...
   $ ./configure --with-ns
   ...
   $ make
   boot=bootstrap-emacs;                         \
           if [ -x "src/$boot" ]; then boot=""; fi;                   \
           cd lib-src; make all                            \
             CC='gcc' CFLAGS='-g -O2 -Wno-pointer-sign  -I/usr/include/GNUstep' CPPFLAGS='-D_BSD_SOURCE  ' \
             LDFLAGS='-Wl,-znocombreloc -L/usr/lib' MAKE='make' BOOTSTRAPEMACS="$boot"
   make[1]: Entering directory `/usr/local/src/emacs/gnustep/lib-src'
   ...
   make[1]: Leaving directory `/usr/local/src/emacs/gnustep/lib-src'
   boot=bootstrap-emacs;                         \
           if [ -x "src/$boot" ]; then boot=""; fi;                   \
           cd src; make all                            \
             CC='gcc' CFLAGS='-g -O2 -Wno-pointer-sign  -I/usr/include/GNUstep' CPPFLAGS='-D_BSD_SOURCE  ' \
             LDFLAGS='-Wl,-znocombreloc -L/usr/lib' MAKE='make' BOOTSTRAPEMACS="$boot"
   make[1]: Entering directory `/usr/local/src/emacs/gnustep/src'
   Makefile:72: /Additional/base.make: No such file or directory
   Makefile:73: /Additional/gui.make: No such file or directory
   make[1]: *** No rule to make target `/Additional/gui.make'.  Stop.
   make[1]: Leaving directory `/usr/local/src/emacs/gnustep/src'
   make: *** [src] Error 2

Thanks,
